1
Multiple Choice
Crossing over between homologous chromosomes during meiosis is significant in heredity. This process most likely leads to an increase in which of the following?
The expression of dominant traits.
Number of gametes.
The occurrence of polyploidy.
Genetic variation.
2
Multiple Choice
During meiosis, homologous chromosomes exchange genetic material. This exchange of genetic material---
increases the genetic variation.
reduces the diploid number to the haploid number.
increases the haploid number to the diploid number.
reduces the probability of mutations.
3
Multiple Choice
A cellular process is shown. Which of these is the most likely result of the process shown in the diagram?
Chromosome replication will increase to avoid errors that result in mutations.
Offspring will no longer express traits from previous generations.
Gametes will contain new allele combinations.
Chromatids will have less genetic variety.
4
Multiple Choice
Gametes produced by an organism contain a combination of genes from that organism. In every gamete, this combination is--
the same because it is created from the same DNA.
the same because chromosomes are copied prior to meiosis.
different due to DNA replication prior to mitosis.
different due to independent assortment during meiosis.
5
Multiple Choice
Which diagram demonstrates how crossing-over contributes to genetic variation during meiosis?
6
Multiple Choice
A cellular process is shown. Which statement best describes the significance of this process?
The process allows organisms to grow and heal.
The process produces clones of the parent organism.
The process copies DNA before cell division.
The process creates genetic variation in the resulting cells.
Crossing over between homologous chromosomes during meiosis is significant in heredity. This process most likely leads to an increase in which of the following?
